The alimentary canal is the passageway for the food we eat : from the mouth to the anus while the digestive system is all those organs plus the others like : kidneys , liver etc. They're both the same. Difference between a human being and an elephants digestive system?
The eartworm's digestive system is : mouth- pharynx- esophagus- crop- gizzard- intestine- anus Meanwhile the grasshopper's is shorter, it is: mouth- esophagus- crop- gizzard- midgut- hindgut- anus.
A polar bear's digestive system is a digestive system and a humming bird is a humming bird. The function of the rectum of a grasshopper is to take the waste products out of the digestive system. There is no difference. Both terms refer to the same system. Digestive system is refferd to by many different names, but mostly digestive system, gastrointestinal GI tract, alimentary canal or dgestive tract.
The difference between the sheeps disgestive system and the humans digestive system is that the sheep is a ruminant and has four stomachs and the human is a monogastric and only has one stomach. I hope this answered your question. The digestive system of a cow and a sheep are the same. Both species are ruminants, and both have the same components and organs of such a ruminant digestive system. Why do you need to know this. The hippo has a three chambered stomach which slowers the speed of the passage of the food.

The material that the organism cannot digest is eliminated as feces, called castings, through the anus. Most invertebrates use some form of extracellular digestion to break down their food.
Flatworms and cnidarians, however, can use both types of digestion to break down their food. Vertebrates may have a single stomach, several stomach chambers, or accessory organs that help to break down ingested food.
Vertebrates have evolved more complex digestive systems to adapt to their dietary needs. Some animals have a single stomach, while others have multi-chambered stomachs. Birds have developed a digestive system adapted to eating un-masticated un-chewed food. Humans and many animals have a monogastric digestive system. The process of digestion begins with the mouth and the intake of food.
The teeth play an important role in masticating chewing or physically breaking down food into smaller particles. The enzymes present in saliva also begin to chemically break down food. The esophagus is a long tube that connects the mouth to the stomach. Using peristalsis, the muscles of the esophagus push the food towards the stomach. In order to speed up the actions of enzymes in the stomach, the stomach has an extremely acidic environment, with a pH between 1.
The gastric juices, which include enzymes in the stomach, act on the food particles and continue the process of digestion. In the small intestine, enzymes produced by the liver, the small intestine, and the pancreas continue the process of digestion.
The nutrients are absorbed into the blood stream across the epithelial cells lining the walls of the small intestines. The waste material travels to the large intestine where water is absorbed and the drier waste material is compacted into feces that are stored until excreted through the rectum. Mammalian digestive system non-ruminant : a Humans and herbivores, such as the b rabbit, have a monogastric digestive system.
However, in the rabbit, the small intestine and cecum are enlarged to allow more time to digest plant material. The enlarged organ provides more surface area for absorption of nutrients. Birds face special challenges when it comes to obtaining nutrition from food.
They do not have teeth, so their digestive system must be able to process un-masticated food. Birds have evolved a variety of beak types that reflect the vast variety in their diet, ranging from seeds and insects to fruits and nuts.
Because most birds fly, their metabolic rates are high in order to efficiently process food while keeping their body weight low. The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground. The undigested material forms food pellets that are sometimes regurgitated. Most of the chemical digestion and absorption happens in the intestine, while the waste is excreted through the cloaca.
Bird digestive system : The avian esophagus has a pouch, called a crop, which stores food. Food passes from the crop to the first of two stomachs, called the proventriculus, which contains digestive juices that break down food. From the proventriculus, the food enters the second stomach, called the gizzard, which grinds food. Some birds swallow stones or grit, which are stored in the gizzard, to aid the grinding process.
Birds do not have separate openings to excrete urine and feces. Instead, uric acid from the kidneys is secreted into the large intestine and combined with waste from the digestive process. This waste is excreted through an opening called the cloaca. Ruminants are mainly herbivores, such as cows, sheep, and goats, whose entire diet consists of eating large amounts of roughage or fiber. They have evolved digestive systems that help them process vast amounts of cellulose.
They use their lower teeth, tongue, and lips to tear and chew their food. From the mouth, the food travels through the esophagus and into the stomach.
To help digest the large amount of plant material, the stomach of the ruminants is a multi-chambered organ. The four compartments of the stomach are called the rumen, reticulum, omasum, and abomasum.
These chambers contain many microbes that break down cellulose and ferment ingested food. This is where gastric juices are secreted. The four-compartment gastric chamber provides larger space and the microbial support necessary to digest plant material in ruminants. The fermentation process produces large amounts of gas in the stomach chamber, which must be eliminated.
As in other animals, the small intestine plays an important role in nutrient absorption, while the large intestine aids in the elimination of waste. Ruminant mammal digestive system : Ruminant animals, such as goats and cows, have four stomachs. The first two stomachs, the rumen and the reticulum, contain prokaryotes and protists that are able to digest cellulose fiber.
The ruminant regurgitates cud from the reticulum, chews it, and swallows it into a third stomach, the omasum, which removes water. The cud then passes onto the fourth stomach, the abomasum, where it is digested by enzymes produced by the ruminant. Some animals, such as camels and alpacas, are pseudo-ruminants. They eat a lot of plant material and roughage. Digesting plant material is not easy because plant cell walls contain the polymeric sugar molecule cellulose. The digestive enzymes of these animals cannot break down cellulose, but microorganisms present in the digestive system can.
Since the digestive system must be able to handle large amounts of roughage and break down the cellulose, pseudo-ruminants have a three-chamber stomach. In contrast to ruminants, their cecum a pouched organ at the beginning of the large intestine containing many microorganisms that are necessary for the digestion of plant materials is large. This is the site where the roughage is fermented and digested. These animals do not have a rumen, but do have an omasum, abomasum, and reticulum.
Animal digestion begins in the mouth, then moves through the pharynx, into the esophagus, and then into the stomach and small intestine. The vertebrate digestive system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms. The upper gastrointestinal tract includes the oral cavity, esophagus, and stomach.
The oral cavity, or mouth, is the point of entry of food into the digestive system. The food is broken into smaller particles by mastication, the chewing action of the teeth. All mammals have teeth and can chew their food. Digestion begins in the oral cavity : Digestion of food begins in the a oral cavity.
Food is masticated by teeth and moistened by saliva secreted from the b salivary glands. Enzymes in the saliva begin to digest starches and fats. With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing. The extensive chemical process of digestion begins in the mouth. As food is chewed, saliva, produced by the salivary glands, mixes with the food.
Saliva is a watery substance produced in the mouths of many animals. There are three major glands that secrete saliva: the parotid, the submandibular, and the sublingual. Saliva contains mucus that moistens food and buffers the pH of the food. Saliva also contains immunoglobulins and lysozymes, which have antibacterial action to reduce tooth decay by inhibiting growth of some bacteria. In addition, saliva contains an enzyme called salivary amylase that begins the process of converting starches in the food into a disaccharide called maltose.
Another enzyme, lipase, is produced by the cells in the tongue. It is a member of a class of enzymes that can break down triglycerides. Lingual lipase begins the breakdown of fat components in the food. The chewing and wetting action provided by the teeth and saliva shape the food into a mass called the bolus for swallowing. The tongue aids in swallowing by moving the bolus from the mouth into the pharynx. The pharynx opens to two passageways: the trachea, which leads to the lungs, and the esophagus, which leads to the stomach.
The tracheal opening, the glottis, is covered by a cartilaginous flap, the epiglottis. When swallowing, the epiglottis closes the glottis, allowing food to pass into the esophagus, not into the trachea, preventing food from reaching the lungs. The esophagus is a tubular organ connecting the mouth to the stomach.
The chewed and softened food passes through the esophagus after being swallowed. The smooth muscles of the esophagus undergo a series of wave like movements called peristalsis that push the food toward the stomach. The peristalsis wave is unidirectional: it moves food from the mouth to the stomach; reverse movement is not possible.
The peristaltic movement of the esophagus is an involuntary reflex, taking place in response to the act of swallowing. Esophagus : The esophagus transfers food from the mouth to the stomach through peristaltic movements.
